摘要：

Single phase LiNixCo1-xO2 (x=0.3) with fine particles were prepared by two low-temperature methods: the modified Pechini sol-gel method and the Self-Propagating Combustion Synthesis (SPCS). It was found that bulk quantities of nano-sized particles of layered LiNixCo1-xO2 could be obtained at temperatures below 400 degreesC by these solutions technique. The synthesized products were characterized by structural (XRD) and thermal (DTA-TG) analyses. HRTEM was used to evaluate the purity and the phase composition of LiNixCo1-xO2. Lattice plane images give information about crystal structure and SAED patterns help us to identify the phase. Nano-crystals were obtained with minimum mean diameter about 5 nm for both methods.
